Explanation:
Iron is found in hematite, an ore with the formula Fe₂O₃.
It goes into a blast furnace, where burning coke and a forced supply of air react to form mostly carbon monoxide.
C + O₂ ⟶ CO₂
C + CO₂ ⟶ 2CO
At the high temperatures inside the furnace, the carbon monoxide reduces the hematite to liquid iron.
Fe₂O₃ + 3CO ⟶ 2Fe + 3CO₂
The iron flows to the bottom of the furnace, where it is drawn off.

Answer:
Kp = \frac{P(NH_{3}) ^{4} P(O_{2}) ^{5}}{P(NO) ^{4} P(H_{2}O)^{6}}
Explanation:
First, we have to write the balanced chemical equation for the reaction. Nitrogen monoxide (NO) reacts with water (H₂O) to give ammonia (NH₃) and oxygen (O₂), according to the following:
NO(g) + H₂O(g) → NH₃(g) + O₂(g)
To balance the equation, we add the stoichiometric coefficients (4 for NH₃ and NO to balance N atoms, then 6 for H₂O to balance H atoms and then 5 for O₂ to balance O atoms):
4 NO(g) + 6 H₂O(g) → 4 NH₃(g) + 5 O₂(g)
All reactants and products are in the gaseous phase, so the equilibrium constant is expressed in terms of partial pressures (P) and is denoted as Kp. The Kp is expressed as the product of the reaction products (NH₃ and O₃) raised by their stoichiometric coefficients (4 and 5, respectively) divided into the product of the reaction reagents (NO and H₂O) raised by their stoichiometric coefficients (4 and 6, respectively). So, the pressure equilibrium constant expression is written as follows:
